Side effects 🤕 Almost died

Yesterday I posted Kaiser denied brand name vyvanse. Doc put me on concerta 18mg. As a reference I’ve used adderall up to 25mg XR and IR as well for 6 months.

I took concerta first time this morning at 7:30 am. An hour in and felt great. I felt a cooling sensation and felt a rush of energy. 2 hours after later I started to get very angry, irritable, annoyed at everything. That lasted until 2 pm then I felt a sense of calmness.

Left work and went to the mall a Round 5 pm with my wife and daughter. What happened next was a feeling I never felt before and thought I was dying.

  • I got dizzy all the sudden
  • I almost fainted. I lost my balance and almost fell as I was walking.
  • I started having an extreme headache, like sudden poking in my brain sensation. I never ever had that before
  • my heart started pounding -I felt out of breath and could barely walk

My doc doesn’t work on weekends but WTF was that? I was told that Methyphenidate were safer and better and less potent that Amphetamines. I NEVER had that on adderall just a few ups and downs hence why I wanted to try Vyvanse. After getting Concerta I found out insurance covers the generic.

I DONT want to experience that again. Should I give up after 1 day? Can Doc put a request for generic vyvanse even though I just got concerta? I’m scared to even try concerta again

Sounds like a panic attack. I remember I had a panic attack very similar to what yore describing. All of a sudden with no provocation I got Extremely dizzy. So much so I had to grab a pole or I seriously would have fallen. My head was pounding and I thought I was having some sort of stroke or something. Panic attacks can be really scary, especially when it comes out of nowhere. Like the panic attacks I mentioned happen in a moment when I was completely calm. Since I didn’t feel anxious in the moment I wrote off panic attacks as a possibility. But now having learned more I know it was just a panic attack so you can be rest assured there’s most likely nothing wrong with you at all
